The AT-AR750S has been designed with the needs of small to medium enterprises/businesses (SME/SMB) or branch office businesses in mind. The AT-AR750S offers significant advances in processing performance, Quality of Service, routing, remote connectivity, and security.The AT-AR750S provides extensive IPSec-based VPN capability, allowing the interconnection of offices, remote tele-workers, and other users who require secure access to a corporate network. The AT-AR750S comes complete with integrated hardware acceleration to maximize encryption throughput and removing the need to purchase a hardware upgrade package. The AT-AR750S is compatible with industry standard IPSec VPN clients.In addition to hardware-based encryption, the AT-AR750S comes with other advanced security features, such as traffic filtering with event logging. Traffic filtering uses the source and destination address, port, protocol and TCP packet type to provide control over traffic that passes through the AT-AR750S. A Stateful Inspection firewall provides an increased level of security and compliments the packet filtering function. HTTP and SMTP proxies on the AT-AR750S provide improved control over web and mail communications.Allied Telesis' QoS implementation enables the AT-AR750S to dynamically identify high priority voice, video and application traffic, so that appropriate service levels can be maintained in congested networks. Advanced QoS allows voice, video, and data traffic to have QoS applied within individual IPSec tunnels, over GRE, as well as IPv6 to IPv4 tunnels.The AT-AR750S provides superior performance over other secure VPN routers in this market space. While most secure routers have stateful firewalls with NAT, QoS, and IPsec VPN termination capability, very few can perform all three functions and still fill the WAN with the small sized packets that occur in real networks. The AT-AR750S has been designed to meet real network needs.The AT-AR750S comes with a comprehensive suite of management features and is also compatible with SNMP-based management packages. An extensive command set is available via the Command Line Interface (CLI), and a browser-based Graphical User Interface (GUI) is also provided to simplify the AT-AR750S' configuration and management. The GUI provides access to default set-ups in key management areas and provides access to regional settings. Allied Telesis' SNMP support extends to SNMPv3 to provide secure management.
